SPECIFICATION formingpart of Letters Iatent No. 423,359, dated March 11, 1890. Application liled April 29, 1889. Serial No. 308,969. (No model.)

To all whom it may concern.-

Be it known that I, AMER'ICUS D. O. VEST, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Hinged-Collar Lamp Attachments, of which the following is a full, clear, and exact description, reference being` had to the accompanying drawings, forming part of this specification.

This invention relates to those devices in which the fianged collar-ring in which the burner is screw-seated is hinged directly tov fastened in parallel slots in the attached col-Z lar, and in outline shows the burner seated in the perforated attachment-collar.` Fig. II is a vertical section of the collar previous to its attachment to the neck of a lamp, and shows the perforated flanged collar -ring hinged thereto and opened upon its hinge. Fig. III is a vertical detail section of the lamp, with its attached collar with my attachment-flanged collar-ring secured thereto by my loop-hinge, and shows in full lines the flanged collar-rin g closed down, and in broken lines shows it elevated. Fig. IV is a side view of the collar that is to be secured by cement or otherwise to the neck of the lamp, and shows the parallel slots to which the loophinge is to be fastened; and FigV is a like view of the attachment-hanged collar-ring, and shows the slot in which the loop of the hinge has loose bearings, and the perforations for the escape of the volatile gases.

Referring to the drawings, 1 represents a detail of the shoulder of a lamp, and f2 its neck, to which the stationary collar 3 is cemented or otherwise rigidly secured.

4 represents the flanged attachment collaris sometimes screwed into the stationary collarv and connected by a screw attachment with the anged collar into which the burner screws, whereas with my direct-burner attachment device, as stated, the flanged attachmentcollar 4 is directly secured to the stationary collar 3, that surrounds the neck 2 of the lamp by the loop-hinge 5, and when folded down on its seat on the stationary collar the peripheral pendent flange 6 of the attachment-collar 4 embraces the rim 7 of the stationary collar to provide a close vapor-tight joint, and the snap-catch 8 on the stationary collar 3 engages in the center-punch recess 9 in the pendent flange of the attachment-collar 4. The said snap-catch and recess are simultaneously made before the collars 3 and 4 have been secured to the lamp vafter closing down the pendent flange 6 of the collar 4 to its seat around the rim 7 of the collar 3 by center-punching the two engaged parts together at. the front side opposite the hinge. The attachment-screw IO of the burner 1l (which burner maybe of any usual construction) is turned into engagement with the screw 12 of the flanged attachment-collar 4.

The loop-hinge 5, that secures the attachment-collar 4 to the stationary collar 31, provides a simple yet efficient means of hinge attachment, which at the same time is less expensive in construction than the hinge now most commonly used, and also provides a buffer-stay to prevent the collision of the burner and flue (when they are thrown back) with the lamp. The hinge is formed by a sheet-metal loop 13, bent to the form shown in Figs. I, II,.and III, the' bow of which has a loose bearing in the slot 14 in the flanged collar-ring 4, and the ends of which are passed through the parallel slots 15 in the stationary collar 3, and are then bent down into angle-flange terminals 16, which are seated in close contact with the inner periphery of the stationary collar 3 and soldered thereto.

IOO

being stayed at that point, it prevents the burner and flue when thrown back from coming into violent contact with the lamp.

The perforations 17 in the flanged collarring 4 provide means for the free exit of the volatile gases that arise from the oil.

Another advantage derived from my lamps is reducing the elevation of the burner above the lamp-reservoir. Again, it will be seen that by the -use'of this attachment, when it.

is required to replenish the lamp With oil, there is no necessity to disconnect the burner, but simply turn back the flanged collar 4, as shown in Figs. I and III, and in broken lines in Fig. IV, in which case the burner is left connected With said collar, and the Whole area of the throat through the neck of the reservoir ot' the lamp is opened up for'pouring in the oil. Thus it Will be seen that not onlyis the necessity avoided ot' removing the burner from the lamp with the Wick pendent therefrom and dripping with oil, but also the aperture provided through which to pour the oil is much larger and more convenient than it is Within the contracted aperture provided by the screw-seat opening in the center ot the flanged attachmen t-collar that is arranged for the insertion of the peripheral screw of the burner. Still, again, it will be seen that when this device is used there are no loose parts provided with the lamp and its attachments, except the bare burner itself. The reservoir, with the collar secured to its neck and its hinged flan ge-collar inseparable therefrom, is of necessity an inseparable provision, needing alone the addition of any burner as provided by the trade, Without having, as is usual, to provide any intermediate part or parts, such as the usual connecting-section.

I claim as my invention- 1. In a lamp-burner attachment, the combination of the stationary collar 3, provided with parallel slots l5, the flanged attachmentcollar 4, that carries the burner, the said collar 4, provided with the slot 14, and the loophinge 5, that Works in the slot 14 of the collar 4 and is seated and secured Within the parallel slots 15 of the collar 3, substantially as described, and for the purpose set forth.

2. In a lamp-burner attachment, the combination of the stationary collar 8,rigidly secured to the neck of the lamp-reservoir, the flanged attachment-collar 4, provided with perforations 17 for the escape of the volatile gases, and provided with thel attachment inner screw l2, with which the peripheral screw of the burner engages, and the loop-hinge 25, Whose bow or loop has free b'earings in the slot 14 in the attachment-collar 4, and whose ilanged ends are secured Within the parallel slots 15 of the collar 3, substantially as described, and lfor the purpose set forth.

3. In a lamp-burner attachment, the coinbination of the -stationary collar 3, rigidly secured to the neck of the lamp-reservoir, the flanged attachment-collar 4, provided With perforations 17 for the escape of volatile gases, the loop-hinge 5, by Which said collar is secured to the stationary collar, the curved peripheral flange that hangs pendent from the collar 4, and Which pendent flange elnbraces the rim of thestationary collar to effect a close joint, and the snap-catch 8 on the stationary collar, Which engages in the recessed countersink in the pendent flange of the collar 4, the loop-hinged connection of the burner attachment-collar 4 with the stationary collar 3, arranged to dispense with all intermediate attachments, substantially as described, and for t-he purpose s et forth.- Y
